Hi Doug,
could it be possible, that the $first_array["second array"] returns
the string "array" instead of the array ??
A possible way to get a copy from your nested array is to write
a function like this:
$new_array = get_nested_array( $first_array, "second array" );
function get_nested_array( $array, $nested_array )
{
while(list($key, $val) = each($array[$nested_array]))
{
$result_array[$key] = $val;
}
return ( $result_array );
}
Yes, there may be a better solution =8)
Greetinx,
Mike

Perhaps I was unclear...I actually _want_ to modify the copy, that's
why I made a copy, to preserve the original. My point was that this
doesn't seem to create a valid copy of the original array:
$new_array = $first_array["second array"];
Operations on $new_array seem to fail, because it isn't an array.
Using a reference would modify the original, and I don't want to do
that.

|
| this modifies the copy!
|
| After applying the modifications, do
| $first_array["second array"] = $new_array;
| to replace the original with the modified contents.
